Joey Barton has been handed a 12 match suspension and a fine of £25,000 after the troubled Newcastle United midfielder admitted a charge of violent conduct over an assault on his then Manchester City team-mate Ousmane Dabo.

An independent Regulatory Commission pronounced the hearing today over the assault that had taken place at City's Carrington training ground on 1 May 2007. The six of the 12 matches, are suspended until the end of the 2009-2010 season and will come in force should the England international be found guilty of any similar charge involving violence or be dismissed from the field of play for violent conduct (but not for serious foul play), said thefa.com.

A statement from the independent Regulatory Commission Chairman Maurice Armstrong said: "Much has been written about Mr Barton over recent months. The Regulatory Commission had the benefit of taking all appropriate information into consideration. The Commission members considered principally the serious attack by Mr Barton that clearly cannot be accepted.

"The members also had to take into consideration the sanctions imposed by the courts and the pro-active support Mr Barton has received from Newcastle United FC and other professional bodies.

"The Commission members wanted to punish the offence appropriately but give Mr Barton an opportunity to ensure his professional conduct does not falter again and ensure he is fully aware of the consequences should he make another serious error of judgement."
